TRANIWAY BUCKET SYSTEM.

Specification of Letters Patent.

Patented any 25, 1905.

Application filed March 28, 1905. Serial No. 252,545.

To all whom it may concern:

Beit known that 1, SEBERN ALLEN CooNEY, a-citizen of the United States,residing at New York city, county of New York, and State of New York,have invented certain new and useful Improvements in Tramway BucketSystems, fully described and represented in the following specificationand the accompanying drawings, forming a part of the same.

This invention relates to that class of tramways in which a bucket isvmoved along a stationary cable or way from which it is suspended by amoving cable to which the bucket is gripped, the bucket being run to thedesired point'along the stationary cable or way and then automaticallydumped.

The invention consists in an improved tramway system in which the bucketisgripped to the moving cable below the bucket and in improved devicesfor automatically dumping the bucket.

In the accompanying drawings, forming a part of this specification, inwhich a tramway bucket system is shown embodying all the features of theinvention as applied in their preferred form, Figure 1 is a side view ofthe bucket with its stationary and moving cables. Fig. 2 is an end viewof the same. Fig. 3 is a side view of the preferred tripping device.Fig. 4 is a detail of the bucket-catch. Fig. 5 is a horizontal sectionon the line 5 of Fig. 1, showing the grip in plan.

Referring to said drawings, A is the stationary cable or way on whichthe automatic bucket B is suspended by wheels 10 and loop 11, forme-d bya continuation of the side frames 12, in which the bucket is pivoted.The side frames 12 have extensions 13 below the bucket connected bycross-bar 14, which carry the grip 15, by which the bucket-frameisgripped to and released from the moving cable O. This grip 15 may be ofIany suitable construction and either single or double, but preferably isa double grip, as shown, so as to hold the bucket-frame atopposite endsand keep it in line with the moving cable, the two parts of the gripbeing shown as connected by link 16, so that both parts of the grip areoperated together by the grip-handle 17. As the particular constructionof this grip forms no part of the present invention, it need not be de-lscribed. Y

The bucket B is hung in the side bars 12,

forming the bucket-frame, by pivots 18, and thebucket is made of suchform as to swing for dumping when loaded and the catch released from theposition shown in full lines to that shown in dotted lines in Fig. v2and to return automatically to the position shown in full lines whenempty.

The bucket B is held in the filling position (shown in full lines 'inFig. 2)4 by the catch, which is shown as formed on catch-arm 19, pivotedon bar 12 at 3 and carrying catch projection 4, which is pressed intoposition to engage catch projection 5 on the bucket by coiled springs 6,these catch projections 4 5 being so formed as to pass each other on thereturn of the bucket to filling position, the catch 4 then being thrownin by the springs 6 to engage catch 5 and hold the bucket, the catchesbeing disengaged to release the bucket for dumping by moving the arm 19sidewise against the tension of springs 6. The arm 19 projects beyondthe front line of the bucket and is engagedfor releasing the bucket bytrip-bar D, which may be positioned at the desired point in any suitablemanner, but preferably is suspended from a stationary cable E by wheel2O on trip-carv rier 21. This carrier 21 is moved along the cable E andsecured in the desired position by small cables or ropes 22, running inopposite directions from the carrier and secured to the stationarycable-supports or other fixed parts of the system.

The operation ofvthe system will be clear from the drawings without anextended description, it being understood that the trip D will bepositioned at the desired point along the cable A by slackening one ofvthe cables 22 and drawing in the other and then securing the cables tohold the trip in place and that the buckets will be dumped successivelyas the arm 19 passes the trip D, moving to the left in Fig. 1 andreturned to position automatically after passing the trip D.

The use of the moving cable below the bucket, so as to be grippedat thebottom of the bucket-frame, secures important advantages overconstructions heretofore in use, especially in connection with theswitching of the bucket from one line to another, the cables being thusplaced at the top and bottom of the bucket-frame, so that there is noobstruction of the bucket by cables in using several connectingbucket-lines. Y

It Will be understood that the invention is not limited to the detailform or construction of the parts illustrated, but that these may bevaried widely within the invention as dened by the claims.

What I claim is- 1. In a tramway bucket system, the combination with astationary cable or way, and a bucket suspended therefrom, of a movingcable below the bucket, and a grip connecting the bucket-frame with themoving cable.

2. In a tramway bucket system, the combination with a stationary cableor way, of an automatically-d u mping bucket suspended therefrom, amoving cable below the bucket, a grip connecting the bucket-frame withthe moving cable, a catch-arm for releasing the bucket, and a tripengaging the catch-arm.

3. In atramway bucket system, the combination Witha stationary cable orWay, of an automatically-dum ping bucket suspended therefrom, a movingcable below'the bucket, a grip connecting the bucket-frame with themoving cable, a catch-arm for releasing the bucket, a stationary tripcable or Way, a trip-bar movable on said trip cable or Way for engagingthe catch-arm, and means for securing the trip-bar in the desiredposition.

4. The combination with a stationary cable or way A, of anautomatically-dumping bucket suspended therefrom, catch-arm 19 forreleasing said bucket,fstationary trip-cable E, suspended tri p-bar Dand trip-carrier 21, and connections Jfor adjusting said carrier on thecable E.

In testimony whereof l have hereunto set my hand in the presence of twosubscribing witnesses.
